Suppose that the number of customers who enter a supermarket each hour is normally distributed with a mean of 640 and a standard deviation of 170. The supermarket isopen 18 hours per day. What is the probability that the total number of customers who enter the supermarket in one day is greater than 12500? (Hint: Calculate the averagehourly number of customers necessary to exceed 12500 in one 18-hour day.)Probability = |
